GAS-LIGHTER. V

' Patented Dec. 12, 1911...

Application filed February 18, 1910. Serial No. 544,545.

To all whom it may concern: I I

Be it known that I, FREDERICK H. PoME- ROY, of Haverhill, county of Essex, and State of Massachusetts, have invented an Im-v provement in Gas-Lighters, of which the following is a specification.

. This invention relates to certain improvements in gas-lighters of the general character shown in my prior Patent, No. 940,27 6, of Nov. 16, 1909, in which a pyrophoric material and an abrader are pressed to-- a sectional view on the line 2-2 of Fig. 1,

portion a increased resilience,

Fig. 3 is a sectional view on the line 3-3 of Fig. 4, and Fig. 4 is a plan view.

. According to my invention I provide a handle comprising a U-shaped spring-wire providing two approximately. parallel arms, a, a, connected by a semi-circular springportion o said arms and said connecting portion being preferably wound with a coiled spring 5 which gives the connecting the united action, of said spring 6 and spring portion a being to swing said arms a art, or hold them in the full line position 0 Fig. 1. The

arm a is bent at right angles at its ends to provide an a'brader-supporting end-portion a on which an abra'der 0, preferably in the form of a cylindrical file having corrugations over its. entire surface, as in my said prior patent, is rotatably mounted. The other arm a has a holder 01, in the form of a tube having a square bore, in the bottom of which a spring e is located, which bears against the inner end of a'piece of pyrophor'ic metal f, which is fitted to slide in thebore ofholder d, and is adapted to have its outer end normally held by said spring 6' a ainst the abrader c. The endortions'o. said arms a, a are preferably mclos'ed in a hoodfljhgwhichacts to collect .of 'a single piece of I accomplish this object by the against by the gas to be ignited about the points where the sparks are to be produced, and serves as a guide for the arms, as they aremoved in relation to each other, and to carry.a stop to ,limitthe extent which they maybe separated. The hood h is preferably formed sheet metal doubled to form .two side-plates h, h', the side h havmg a transversely-extending tongue h which is bent about the arm a, so as to secure the same thereto, the end of said tongue being soldered or'otherwise firmly secured to the inner surface of the side 71 A Stoplug c is provided on the side h which is adapted to engage the holder d andlimit the vmovement thereof at the pointindicated by the full line position of Figs. 1, 2 and 3.'

The side It is provided with'one or more v openings, as h, h, the portion opposite the abrade'r, said portion being somewhat distended to provide a gas-receiving chamher, and the other portions of the sides are arranged to form a straight guide-way for the holder (Z as it is moved toward and from the arm a.

The operation of the above-described device is as follows: The device is held so that the gas will enter the openings h, h, and fill the hood h, and then the arms a, a are pressed together, causing the '-pyrophoric material f to be carried over the the abrader 0, while firmly pressed therethe spring 6, thereby causing the Sparks to be produced an'dt-he gas to be ignited.

WVhile the end of the tubular holder 03 will not be carried in exact parallelism with the surface of the abrader, it will be carried in approximate parallelism therewith, and any variations in this regard will be compensated for by the spring e, which will force the material f from the holder where necessary to maintain an even pressure of the material on the abrader.

As the-entire surface of the abrader o is corrugated, by rotating the abrader to different positions on the end portion aflfresh abrading faces are presented to the material f, so that when one face becomes worn another may be used;

Wh'ile' I have shown and described the arm a, bearing the abrader, as ermanently secured to the hood, yet it will be apparent that a form of connection may be em loyed,

which will enable the hood to be rea ily desurface of tached therefrom, so that a fresh piece of pyrophoric material maybe placed in the holder. It will also be apparent that it is of little or no practical consequence which arm is secured to the hood, provided the hood is, properly arranged with relation thereto.

-I claim I 1. A gas lighter comprising a pair of arms adapted to swing laterally toward and fromeach other and a-pyrophoric material holder mounted on one arm and movable therewith, anj abrader connected to the other. arm and means for holding the material n sald holder and the abrader in 'engagementouring a predetermined relative swinging movement of said arms, substantially as described.

" '2. A gas lighter comprising a pair of arms adapted to be swung toward and from each other, an abrader connected-to one of said arms and disposed to extend transversely thereof, a pyrophor-ic material holder on the other arm and means for holding the material in said holder and the abrader in engagement as said arms are relatively moved, substantially as described. 3. A gas-lighter comprising a. pair of arms extending in approximate parallelism and having an intermediate spring nor-.

mally acting to swing said armsaway from each other, an abrader connected to one of said arms-and extending transversely thereof toward the other arm, means on the latter arm for holding a pyrophoric material in engagement with said abrader as said arms are swung relatively to each other, and

a stop for limiting the separation of said arms, substantially as described. a

4. A gas-lighter comprising a spring-- wire bent in U-form to provide a pair of arms extending in approximate parallelism, a stop on one of said armsforlimiting the separation thereof under the action of said ;,spring, 'an abrader on one of said arms extending transversely thereof, and means on the other arm for sup orting apyrophoric material and for y1e dingly pressing the same longitudinall thereof against said abradenjsiibstantia y as described.

5. Ai-gas-lighter comprising apai-r of relatively-swinging arms spring-actuated to separate the ends thereof, an abrader on one arm, a pyrophoric material supported on.
